Sorry if I was not clear.

Memtest very useful in finding errors within the RAM stick. But
it does not test the RAM when the rest of the server components
are under load and so may not find some obscure problems.

Some problems do not occur when each element of a system is tested
in isolation, only when they are combined or placed in certain
enviromental conditions. Drives engineers crazy.
;)

Back to the Shuttle boxes. They are useful bits of kit, especially
for crowded workplaces, but they seem to have a lifetime of about
4 years.

In the workshop are some spare bits from various dead Shuttles.
If let me know the model I may be able to find some bits.
